Hi,

I found the cause, issue solved. The cause was the rename of an addon directory and had nothing to do with the shop configuration. The error in the webpage does indicate a symptom only.

Maybe the error message in the view can be improved.

The cause must have been that the anchor for the relative addressen /web/... was corrupt.

The server log said:
